I'm attempting to install Programmers Dvorak on Windows XP, however, I am meeting with no success. I can download and run the binary, and it gives me the prompt asking if I wish it install programmers Dvorak, at which point I see a loading box flash fairly quickly, then disappear.

I receive no message it installed, or that it has come across any sort of error - but "Programmers Dvorak" does not appear as a possible Keyboard layout, so it is fairly evident something went wrong during installation.
